Hi Friends,
Although phpxref based code documentation is available on this website itself. It makes easy to browse code with top level domain.
You may browse nucleus cms 3.33 version code here. Requesting moderators to make this topic sticky.

I agree with Armon on this one. There's no value added by the code documentation on this site compared to what is already available. Seems it's just someone trying to make ad money by displaying other people's code.
